B7-1/CD80 Antibody (37711) [PerCP]

The B-lymphocyte activation antigen B7-1 (CD80) provides regulatory signals for T lymphocytes as a consequence of binding to the CD28 and CTLA4 ligands of T cells. After engagement of T-cell receptor with antigen in association with major histocompatibility complex class II, a second signal mediated through the binding of B7 to CD28 greatly upregulates the production of multiple lymphokines (1). The relatively small CTLA-4/B7-1 binding interface exhibits an unusually high degree of shape complementarity. CTLA-4 forms homodimers through a newly defined interface of highly conserved residues. This zipper-like oligomerization provides the structural basis for forming unusually stable signalling complexes at the T-cell surface, underscoring the importance of potent inhibitory signalling in human immune responses (2).
